Detailed Description

The invention will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present invention and are not intended to limit the scope of the present invention. Further, it is understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the present invention, and such equivalents are intended to fall within the scope of the claims appended hereto.

With reference to fig. 2, the present embodiment takes a steel structure factory building as an example to clearly and completely describe a linkage structure design method based on data driving, which includes the following steps:

step 1, data preprocessing

Firstly, the construction and process investment drawing is preprocessed to obtain CAD axial net and CAD wall hole investment drawing, and needed design data such as STS calculation model and the like are obtained from domestic structure calculation software.

Step 2, data analysis

Material information is obtained according to project design specifications, roof supporting distance is obtained according to the shaft net, and gear, flanging and other information of the purline enclosing structure are obtained according to the shaft net, the hole height and other information. The data analysis method can fully utilize various data related to the structural design, and improves the scientificity and reliability of the structural design.

Step 3, linkage design

The door rigid structure is decomposed into subsidiary structural modules such as rigid frames, roof supports, roof purlines, column supports, wall purlines, wind-resistant columns/sandwich beams, awning, adjacent houses and the like, and then information obtained according to data preprocessing and data analysis is input into a development tool. For example: the rigid frame structure module determines the positions of the ridge and the cornice through structure calculation software, and connects the positions to generate a main rigid frame line; the roof supporting structure module obtains intersecting points of a transverse axis and a longitudinal axis through a shaft network, sorts and groups the intersecting points according to the sequence of an x coordinate and a y coordinate, gives parameters such as elevation and the like in a z direction, automatically calculates roof gradient, copies points to roof ridges and roof and cornice positions, and can obtain tie bars and space lines of the supports in the roof support according to the support distance of the roof; the roofing purline structure module generates corresponding points on the roof according to gear positions of a purline maintenance structure and main rigid frame lines, the points are connected in parallel to the ridge direction to form purline space lines with intervals, the reinforcing beam lines are generated at the position of the hole to extend to other lines, whether the hole passes through and breaks certain purlines is judged, and the starting and ending positions of the lines of surrounding purlines are replaced to achieve a flanging effect; the line generation of the inter-column support structure module is similar to roof support, and the line is formed by connecting intersection points of ridges or cornices of intersection points of the shaft net; the generation of the wall purline structure module is similar to that of a roof purline, and parameters such as holes, flanging and the like are also required to be processed; the other auxiliary structure modules are generated by moving known points and connecting the known points to form space lines, the space lines are obtained in length, the space lines are numbered and cross-sections are matched in a grading mode according to the lengths, the space lines are automatically given with the numbers and the cross-sections, the components are generated in BIM software respectively, each structure module is further formed, and the structure modules are organically combined together to form the whole door rigid model.

The linkage design method is that all received information is analyzed and calculated, so that lines of the components in the space are generated, and the lines comprise position information, section information, eccentric information, direction and orientation information, numbering information, state filtering information and the like of the components, and the lines are reflected in BIM software. Any input information is modified, the associated rod members can be modified in a linkage way, and each structural module is in an organic design whole, so that the whole monomer is formed.

According to the linkage type design method, interaction among all modules of the structure can be fully considered, the harmony and consistency of the result are optimized, and the efficiency and accuracy of the structure design are improved.

Step 4, design optimization

The section generated by structural calculation can automatically generate a section and a number meeting the conditions according to the mechanical property, and other rod lengths can automatically perform section grading and numbering according to the results of data preprocessing and data analysis and give the members.

After the calculation software or the planar CAD drawing is modified, the BIM software can modify the corresponding information such as the rod piece, the hole, the elevation, the shaft net, the purline gear and the like in real time, and the efficiency of a designer is improved.

Design optimization can link design modification to a model in real time, reduce the workload of designer modification, and improve design and drawing quality.

The invention provides a linkage type structural design method based on data driving, which can drive and generate a BIM model by extracting data such as calculation software, process investment drawing and the like, and the obtained structural design model can be automatically modified according to the modified investment drawing and the calculation model, so that the work of manual modeling and modification is saved, and the efficiency of structural design and the quality of final delivery results are improved.
